Dish: that's daddy's girl! (6)
I believe the answer is:
paella
'dish' is the definition.
(type of meal)
'daddy's girl' is the wordplay.
'daddy' becomes 'pa' (synonyms).
'girl' becomes 'ella' (girl's name).
'pa'+'ella'='PAELLA'
'that's' is the link.
(Other definitions for paella that I've seen before include "Span. rice dish" , "foreign dish" , "Spanish dish of rice, shellfish, etc" , "Al, leap into the Spanish dish" , "Meal" .)
